If you are looking for discounts on the 2016 or 2017 range of mountain bikes from Raleigh, they can be quite difficult to find, as the number of models appears to have been carefully selected to sell well. The two main models are the All Terrain series and the MTrax series, so the best time to look for Raleigh MTB sales is probably going to be around the time when the 2018 bikes start to get publicity.
We haven't found any of these bikes at discount at the moment, but there are 0 bikes on sale which you can see using the link above or the left hand menu.
This is a range of all-terrain hardtail leisure mountain bikes at an entry price point, with some increasing level of specification as you go from the AT05 up to the Rayleigh AT30. That means the use of disc brakes instead of V-brakes and an increase in the number of gears from 18 to 24 to allow more versatile mountain biking.
